HEAD AND NECK CANCER Kenyatta National Hospital Research Symposium 13th April 2012
What are they? • Cancers of following anatomical sites: • Oral cavity • Nose & paranasal sinuses • Oropharynx • Hypopharynx • Nasopharynx • Larynx • Cervical oesophagus • Salivary glands • Soft tissues of the neck & ears
The Burden • Very common • Worldwide: • 5% of all newly diagnosed cancer cases • 640,000 cases per year • 35,000 deaths per year • Locally: • No prevalence or incidence figures • Second commonest malignancy reported after cancer of cervix in 2000-2002
Risk Factors • Smoking and tobacco use • Alcohol consumption • Gastroesophageal reflux disease • Human papillomavirus • EBV • Radiation exposure • Genetic factors • Diet • Environmental pollutants • Socio-economic status
Screening? • No evidence for an effective screening programme • Calls for stepping up public awareness: • Clinicians • public
Age/Sex distribution • Males more than females • Incidence tends to increase with age • Majority (85%) over 50 yrs in UK
Warning symptoms & signs • Persistent: • Red/white patches in oral cavity • Swelling in neck – usually painless • Ulcer/swelling in oral cavity or oropharynx • Abnormal tooth mobility • Throat discomfort • Hoarseness • Dysphagia/odynophagia
Warning symptoms & signs • Serosanguinous nasal discharge • Unilateral nasal blockage • Unilateral hearing loss • Facial weakness/numbness • Unexplained ear pain • Orbital swellings • Changes in a mole
Work-up • History • Physical examination • Investigations:- • Haematological • Radiological: • CT-Scans/MRI • U/S • Plain x-rays • Histological • Staging
Management Considerations • Morbidity • Function • Cosmesis • Quality of life
Challenges of HNC • Late presentation/confusing symptoms • Nutritional issues • Airway issues • Availability/affordability of diagnostic facilities • Compliance • Follow-up
Treatment Options • Curative or palliative: • Surgery: • Laser • Endoscopic • open • Radiotherapy: • External beam • brachytherapy • Chemotherapy • Combinations
Multidisciplinary Head & Neck Team • Otolaryngology • Maxillofacial • Plastic & Reconstruction • Neurosurgery • Cardiothoracic • Anaesthesia • Pathology • Nursing • Radiology • oncology • Counselling • Nutrition
Before surgery After surgery – Deltocervical flap Parotid Tumor
Before Surgery After Surgery - FFF Ameloblastoma
Before surgery After surgery - Buccinator flap Oral Carcinoma
Before Surgery After Surgery – Pec major flap Skin Cancer
Intra-operative After surgery - FRFF Tongue Cancer
Pre-operative After surgery – pec major flap Osteoradionecrosis
Challenges of Management • Waiting time for cancer patients remains long • Post-operative care of free flaps • Pathology services:- • Frozen section • Inadequate reporting on margins, nodal status, vascular invasion, neural invasion • Delayed reports • Lack of equipment & materials • Post-operative radiation waiting time
The Future • Research • Technology
